I indeed forgot that old patch. I will rebase and apply it first, so 
this patch will need some rebasing as well.

One note about the patch: doing the capability check on every single 
frame seems wasteful. I'm not sure how slow it is, but I'd expect it to 
be not free.

So doing that check once in the beginning with all the other cap checks 
and storing it somewhere would be better.
